   the Phase 15 schema and could be built in parallel with Phase 16 (EML
   parser) if split across two workstreams — sequenced after 16 here for a
   single execution thread
+
 - The durable schema (campaigns/reports/messages/indicators/classifications/
   remediation_actions/audit_events) lands in Phase 15, before any service
   that writes to it — new migration, next number after 096 (097+)
+
 - ACCESS-01 is mapped to Phase 18 (the first phase introducing
   `/api/phishing/*` routes) rather than a standalone terminal phase; every
   later phishing endpoint (19, 20, 21) is expected to continue enforcing the
   same `requireAuth`/`requirePermission` convention as a success-criteria
   carry-forward, not a re-mapped requirement
+
 - Classification (Phase 19) is sequenced after both Phase 17 (blast-radius)
   and Phase 18 (campaigns) since it needs both as inputs
+
 - Remediation/approval/audit (Phase 20) is sequenced after Phase 18
   (campaigns) and Phase 19 (classifications) — can't approve/gate an action
   that doesn't reference either
+
 - Autotask triage note (Phase 21) is last — its content summarizes
   classification + blast radius + recommended/approved remediation state,
   so it has nothing to summarize until Phases 19-20 exist
